Halfway Between 67 and 636

When you ask "What number is halfway between 67 and 636?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=67 and Y=636.

Halfway Between Line

To find the number halfway between 67 and 636, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 636 into our formula, we get:

(67 + 636)/2 = 351.5

Thus, the number halfway between 67 and 636 is 351.5.

To check that our answer is correct, we subtract 67 from 351.5 and subtract 351.5 from 636 and compare the two numbers:

351.5 - 67 = 284.5
636 - 351.5 = 284.5

As you can see, the halfway number is 284.5 higher than 67 and 284.5 lower than 636. Therefore, our halfway between answer of 351.5 above is correct.
